Super Micro says AI server demand pushed its quarter to as much as $19.5 billion, about $4 billion above its own forecast

Super Micro Computer said on Tuesday, Oct. 20, 2026, that it expects revenue of $18.5 billion to $19.5 billion for its fiscal first quarter ended Sept. 30, well above its own guidance of $14.5 billion to $15.5 billion, which it attributed mainly to increased demand for AI platforms.

When a server maker beats its own forecast by roughly a quarter, the money behind the AI build-out is still showing up as real purchase orders, not just announcements. It's a useful counterweight to last week's CoreWeave wobble. The catch is in the margin: even "beating" means keeping about 12 cents of every sales dollar before overhead, because Supermicro mostly bolts Nvidia's expensive chips into racks. It sells a lot of AI. It doesn't keep much of it. And companies don't usually pre-announce two weeks early unless they want the good news out first.

Super Micro Computer, which trades as SMCI on the Nasdaq, estimates revenue of $18.5 billion to $19.5 billion for its fiscal first quarter of 2027, the quarter that ended Sept. 30, 2026. Its own guidance for that quarter had been $14.5 billion to $15.5 billion. The new range sits $4 billion above the old one at both ends. The company said the difference is "primarily due to increased demand for AI platforms." Those figures are Supermicro's, and they are estimates.

Gross margin is estimated at 12.0% to 12.5%, versus guidance of 10.4% to 10.8%, "primarily due to customer and product mix." Gross margin is what remains of a sales dollar after the direct cost of the goods, before overhead, research, and interest. At about 12%, the company keeps about 12 cents of each sales dollar at that step. Those figures are Supermicro's estimates.

The company says the numbers are preliminary, unaudited management estimates and may change. Its auditor has not reviewed them. Full results, and a conference call, are set for Tuesday, Nov. 3, 2026, at 5 p.m. Eastern. Bloomberg reports that the company gave no reason for announcing early. The limits are Supermicro's. The missing reason is Bloomberg's.

Analysts had expected less. The average revenue estimate was $15.23 billion, from LSEG, as Reuters reports it. Bloomberg's compiled average was about $15 billion. Analysts expected a gross margin of 10.15%, Reuters says. Those are the analysts' averages, as the wires cite them. They are not Supermicro's results.

The stock rose about 11% in after-hours trading after closing at $32.47. Reuters puts the after-hours move at 11.3%. Bloomberg puts it at about 12%. Dell and HPE gained 3.5% to 4.9%, and Nvidia rose 1.5% after hours, Reuters reports. Supermicro's servers are built around Nvidia chips. Those moves are Reuters's and Bloomberg's.

Reuters sets the week around the number. AI data-center stocks fell last week after a slide in CoreWeave's stock and bonds, and after worries about higher interest rates. Microsoft, Google, Amazon, and Meta are expected to spend more than $700 billion on AI infrastructure this year. That spending figure is an expectation Reuters reports. It is not a Supermicro forecast, and it is not money Supermicro says it has already booked.

In plain terms, Super Micro said on Tuesday that the quarter looks like $18.5 billion to $19.5 billion of revenue, about $4 billion above the forecast it had given, with gross margin looking like 12.0% to 12.5% instead of the 10.4% to 10.8% it had guided. Both figures are preliminary. The company did not report profit, earnings per share, guidance for the next quarter, customer names, or a backlog. The full report is scheduled for Nov. 3.
